Disconnected from a very dry page — boring (6)
I believe the answer is:
abrupt
'disconnected' is the definition.
(synonyms)
'a very dry page boring' is the wordplay.
'very dry' becomes 'brut' (term for very dry wine).
'page' becomes 'p'.
'boring' is an insertion indicator (some letters must 'bore' a hole into other letters).
'brut' going around 'p' is 'brupt'.
'a'+'brupt'='ABRUPT'
'from' is the link.
(Other definitions for abrupt that I've seen before include "Brusque, curt" , "brisk" , "Rough and quick" , "Sudden, maybe rude" , "Short in manner" .)
